Characterizing High Speed Interconnects with Channel Operating Margin (COM) and Effective Return Loss (ERL)

3/12/2020

COM (channel operating margin) and ERL (effective return loss) are two complicated figures of merit that are required compliance measurements for high speed NRZ and PAM4 Ethernet interconnects. Both are derived from S-parameters but involve modeling of noise, SerDes package response, equalization, and crosstalk.

Watch this webiar to learn how COM and ERL can be used to analyze the interoperability margin of high speed serial systems and the performance of different designs.
